This invention relates to line guiding devices,

and more particularly to an improved line guiding'means adapted for use with binders or the like.-

%; An ob'j'ectof this invention is to provide an improved line guidei'n the form of an attachment which may bejreadily and quickly applied to the present parts of a binder and which is so con- 7 struct ed 'that the friction of the line passing Iii) tlirouglr the'guide will not form a groove therein.

Another object of this invention is to provide a line guidewhi'ch may be constructed from glass or the like and which includes a novel attaching means, whereby the guide may be readily and 'i quickly attached to the present parts of a binder without disturbing the body parts. n

A further object of this invention is to provide animproved line guiding means for the needle of a binder wherein the line is supported partly on 0 rotatable glass guiding rollers and partly on stationary glass-eyes so that thepassage of the line through the stationary eye and the rotatable guide members will not cause grooves to be formed therein as is at present the case.

Still another object of this invention is to providea line guiding eye which is formed of glass or thelike and which includes a novel clamping means which not only detachably holds the eye or guiding member therein, but also holds the glass eye or guiding member on the present parts of the binderstructure.

To the foregoing objects and others which may hereinafter appear, the invention consists of the 'novel construction, combination and arrangementof parts as will be more specifically described and as illustrated inthe accompanying drawing, wherein is shown embodiments of the invention, but it is to be understood that changes, variations and modifications may be resorted to whichfall within the scope of the invention as claimed.

Figure? is" a vertical section of a guide roller 5 constructed according to an embodiment of this invention.

Referring to'thedrawing, the numeral Ill designates generally a needle'at present forming part of a binder structure which is secured to an operl0 ating shaft 5. The needle I8 comprises a radial arm I52 and an arcuate member I3 secured to the outer end thereof, which, is pointed at one end and this needle is adapted; tov be rocked in a conventionalmanner by rocking or rotation of the operl5 atingshaft II.v

A. guide member is secured to the radial arm I2 adjacent the inner end thereof and comprises an arm Ii'having, an eye or annulus I6 secured to the outer end thereof. This arm [5 is secured to the 20 radial arm I2 by means of a'rivet or fastening member H. The structure hereinbefore described is at present conventional structure in a binder anda binder twine or cord I8 is adapted to be passed through the eye IS-andis then guided over rollers I 3-to the pointed end of the needle I3. The eye l6 at present is formed of metal and the friction caused by the passage of the twine I8 therethrough forms a groove or channel on the inside of the eye so that when knots or enlarged por- 3 tions in the twine I8 pass through the eye I6 these knots or enlarged portions tend to cause breakage of the twine or in other ways tend to retard the free movement of the twine or cord I8 through the end of the needle.

In order to provide a means in combination with the eye It whereby the twine I8 may freely pass therethrough, I have provided an annulus generally designated as 20 which is disposed concentrically of the eye I6. This annulus 20 comprises a glass sleeve 2| which is provided with rounded opposite end portions 22 in the bore thereof and which is also provided with a rib or bead 23 at its outer end. The sleeve H is provided at its inner end with a seat 24 adapted to engage the rounded surface of the eye I6 so that the sleeve 2| may snugly rest on thiseye I6 and be held concentrically thereof.

The guiding member 20 is detachably clamped on the eye or annular member I6 by a clamping 5 device generally designated as 25. This clamping member 25 comprises an annular base member 26 provided with a plurality of upstanding clips or arms 21 which are adapted to engage about the rib 23 as shown in Figure 2. The clips 21 are struck from the annular member 26 on the inside thereof and are then bent outwardly at substantially right angles, being formed adjacent their outer ends with curved portions 28 which are adapted to engage about the bead 23. A plurality of circumferentially spaced apart clips or clamping members 29 are struck from the blank of which the clamping member is formed and have a configuration substantially coincident with the configuration of the eye l6. Initially as shown in Figure 5 these clamping clips 29 are straight and are then bent in substantially the configuration shown in Figure 4. The base member 26 is adapted to engage one side of the eye |l6 so as to support the guiding member 20 and the clips 29 firmly hold the base 26 in concentric position on the eye Hi.

In Figure 6 there is disclosed a modified form of guide member wherein a sleeve 2| is provided which is adapted to engage within and extend through the guide eye I6. The sleeve 2| is provided with a bead 23' at one end and a clamping member 25 similar to the clamping member 25 disclosed in Figure 4 is secured to the guiding member 20 so as to detachably holdthe guide member 20' on the guide eye Hi. In this instance, the ends 30' of the attaching clips engage below the eye l6 and may project inwardly a sufiicient degree to contact with the adjacent end of the sleeve 2|.

In Figure 7 there is disclosed a glass roller 3| provided with a peripheral groove 32 and this roller 3| is provided in the bore thereof with a metal sleeve 33 which has the opposite ends thereof outturned so as to provide flanges 34. In this manner the flanges 34 act as protecting means and as spacing means for spacing the adjacent ends of the roller 3| from the needle l3 and also from the head of a securing member 35. In the present instance, the securing member 35 is disclosed as a screw, but it will be understood that this member 35 may also be in the form of a headed rivet or the like. The provision of a metal sleeve or bushing 33 on the inside of the roller 3| provides a wear surface for the roller 3| so that the roller 3| will not cut into the surface of the bolt or rivet 35.

In the use of this line guiding means the rollers at present in use on the needle l3 may be removed and the glass rollers 3| substituted therefor. The conventional guide member I 6 with the support l5 may be retained on the radial arm l2 and the clips 29 engaged over the outside of the eye l6 so as to firmly hold the guide member 20 concentrically of the old guide eye l6. Preferably, the bore of the guide member 20 is relatively smaller than the bore of the eye l6 so that the twine I8 will not have a tendency to contact with the surface of the guide member 5 in the movement of the twine through the eye or guide member 20. g

This line guiding attachment is so constructed that it can be easily and quickly mounted on the present guide |6 of the binder without changing or in any way disturbing the present construction of this guide member |6. Through the use of glass or similar substance, the guide 20 will not have a groove formed therein caused by friction of the line passing therethrough as is the case where a metal guide eye is used. This guide attachment will therefore provide a guiding means for the twine which will have a life substantially equal to the binder, thus making it unnecessary to stop the operation of the binder due to the breaking of the twine as it passes through the eye which may be formed with a groove therein due to the friction of the line in the eye.

What I claim is: I

A line guide comprising an annulus, a ringshaped base member, circumferentially spaced apart resilient clips carried by and disposed substantially at right angles to the inside periphery of said base member engaging said annulus to hold said annulus on said base member, and circumferentially spaced apart resilient clips carried by and disposed substantially at right angles 7 to the outer periphery of said base member and extending oppositely with respect to said first clips to detachably hold said base member on a support.
